Poppi Pipopapo was created to serve as a guide to the riders in CR. She provides insight on the Bugster viruses, the Rider system, and helps to transfer patients to CR if the situation requires it. Poppi's true personality is bubbly and energetic. As Asuna, however, she takes on a mature and no-nonsense persona, although her normal personality will momentarily surface if she is addressed by her real name. But there have been times when Poppi as Asuna reverts to her true personality on her own free will.
